Reservations for up to 2 million people per hour can be made through the domestic COVID-19 vaccination advance reservation system.

In a joint briefing with the Ministry of Science and ICT, the Ministry of Public Administration and Security, and the Ministry of Public Administration and Security on the 5th, the Corona 19 Vaccination Response Promotion Team announced that it had improved the advance reservation system through public-private cooperation to resolve errors such as the 'eaten situation'.

The promotion team expects to improve the reservation processing performance from 300,000 to 2 million per hour by enabling smooth access through server expansion and relocation and database efficiency.

In the pre-reservation for general young and middle-aged adults aged 18 to 49, which will start in the form of a '10 sub-system reservation' on the 9th, it is expected that the reservation will be completed in 30 to 50 minutes even if the maximum number of people log in at the same time.

If the '10 system reservation' is introduced, which divides the reservation date over ten days based on the last digit of the date of birth of the resident registration number, the number of reservations will be distributed at a maximum of 1.9 million (11.7%) per day out of 16.21 million as of 00:00 today.

Based on the ten-subject reservation system, 'diversification of personal authentication methods' and 'restriction of proxy reservations and simultaneous access' are also introduced, which will enable smoother access than before.

This time, you have to verify your identity first and then wait for a reservation, but you can do it quickly through a simple certificate rather than a mobile phone, i-PIN, or joint/financial certificate.

In particular, real-time status information for each authentication method is displayed in green (smooth), yellow (delayed), red (congested),Traffic light methods such as gray (not selectable) can be seen at a glance, so you can choose a way to avoid congestion.

Reservations can be made from 8:00 p.m. on the same day to 6:00 p.m. the next day, but authorities explained that reservations can be made quickly if used after 9:00 p.m.

The promotion team is planning to expand the means of self-authentication 9 days before the start of the '10-subject reservation' and transfer the self-authentication function, which was considered the biggest overload factor when accessing the reservation system, to the private cloud.

When these follow-up actions are completed, the maximum throughput per hour is expected to reach approximately 2 million people and the waiting time for reservations is expected to be further reduced.

In the case of seniors over 60, their children cannot make a proxy reservation through the reservation system.
